4-Cycle Tiller Maintenance (Continued)
A wet or dirty air lter can affect the way your engine starts, performs, and wears.
Check your air lter once a month or after every 10 hours of use.
Note: If you work in dusty soil, check your lter more often (for instance, before
each use). Be sure to replace it if its worn out or damaged.
How to Check, Clean, and Change the Air Filter
AIR FILTER MAINTENANCE
Figure 1 Figure 2
1. The air lter is held in the air cleaner in a black housing on the side of the Tiller,
behind the gas tank cap.
2. Squeeze the two locking tabs at the rear of the air cleaner cover (Figure 1) and
swing the cover toward the front of the engine to open it.
3. The air lter is the dark, sponge-like material on the inside of the air cleaner.
4. If the air lter needs to be cleaned (i.e. if it is soiled or moist), or no longer ts
properly, simply remove it by carefully peeling it out of the air cleaner. (Figure 2)
5. To clean the air lter
a. Clean the lter element in warm, soapy water then rinse and allow to dry
thoroughly. It also can be cleaned with a non-ammable solvent.
b. Dip the lter element in clean engine oil then squeeze out any excess oil.
Note: The engine will smoke when started if too much oil is left in the element.
c. Wipe dirt from the air cleaner body and cover using a moist rag. Note: Be
careful to prevent dirt from entering the carburetor.
6. Replace the clean lter inside the air cleaner.
IMPORTANT:
Make sure the lter is “seated”
properly in the cover. The lter
must t snugly inside the open-
ing that holds the lter in place.
Installing the lter incorrectly will
cause engine damage and void
the warranty. Fit the cover back
over the air cleaner and snap the
two locking tabs.
IMPORTANT NOTE:
A dirty air cleaner will restrict air
ow to the carburetor, reducing
engine performance. If you oper-
ate the engine in very dusty areas,
clean the air lter element more
often then specied in the
Maintenance section.
IMPORTANT NOTE:
Operating the engine without an
air lter element, or with a dam-
aged air lter element, will allow
dirt to enter the engine, causing
rapid engine wear. This type of
damage is not covered by the
Limited Warranty
IMPORTANT NOTE:
Check the lip on the Air
Cleaner Cover. If the lip is chipped
or cracked, it should be replaced.
This will prevent dirt from being
drawn through the carburetor into
the inside of the engine.
